The first section of the PDR to be completed was the Southern Way Link Road in 1978 and the latest section was phase 1 of the Eastern Bay Link Road, known as Ewart Parkinson Road in 2017. When fully completed, the road will form part of the Cardiff ring road system. The PDR runs west, south and east of Cardiff, with the M4 between junction 30 and junction 33 completing the northern section. The PDR is dual carriageway for its entire length except for Rover Way and the East Moors Viaduct, which is a single carriageway. The entire length of the road has clearway restrictions on it.
The PDR has been constructed in separate link roads of between 1.2 km (0.75 mi) and 5.47 km (3.40 mi) around Cardiff and to date 17.4 miles (28.0 km) including spurs have been opened to traffic, with plans for a further 5.53 km (3.44 mi). It has 5 large viaducts (Ely Viaduct, Grangetown Viaduct, Taff Viaduct, Eastern Bay Link Viaduct and the East Moors Viaduct), 1 tunnel (Queen's Gate Tunnel) and 2 spur roads (Cogan Spur and Central Link Road). The road has many grade separated interchanges.
